Introduction
Foam pigs, offered by EMT, are highly versatile pipeline cleaning devices. These tools are essential in industries like oil and gas, municipality, and food and beverage, as well as in mining, chemical and petrochemical, cosmetic, and pharmaceutical sectors. Due to their lightweight and flexible nature, EMT’s foam pigs easily navigate through unusual piping, fittings, and valves. Their sizes vary from 2″ to 60″, and they come in three foam densities: light (1-2 lbs/ft³), medium (5-7 lbs/ft³), and heavy (8-10 lbs/ft³).
Moreover, EMT provides various configurations such as bare, criss-cross, wire-brush, plastic bristle, and silicon carbide. Options include double-dish, double-nose, and special coating patterns like single-spiral, turning pattern, and totally coated. Additionally, we customize lengths and diameters, and offer features like pulling/handling ropes or cables, bypass jets, and transmitter cavities. EMT can design special configurations to meet unique pigging needs. For detailed technical specifications, please check the downloadable sheets in our technical data section.
Different Types Of Foam Pigs
Light Density Foam Pigs (1-2 lbs/ft³): These are the most flexible and lightweight options. They excel at light cleaning and drying operations, easily navigating through tight bends and smaller diameter pipes. Due to their softness, they are perfect for delicate or newly constructed pipelines where minimal abrasion is crucial.
Medium Density Foam Pigs (5-7 lbs/ft³): These foam pigs strike a balance between flexibility and sturdiness. They are ideal for more thorough cleaning tasks and can remove medium-level deposits. Their increased density makes them suitable for longer pipeline sections, providing a good mix of scrubbing power and the ability to pass through reduced clearances without getting stuck.
Heavy Density Foam Pigs (8-10 lbs/ft³): These are the most robust and densest foam pigs available. They are designed for challenging cleaning jobs, such as removing heavy deposits and scale from pipelines. Their toughness allows them to withstand substantial pressure differences and aggressive cleaning environments, making them ideal for older or more contaminated pipelines.
Each density type serves a specific purpose, ensuring that pipelines remain clean and functional regardless of the condition or complexity of the system.
